Watch: RuPaul Shares Top 3 Most Shocking 'Drag Race' Moments

The "RuPaul's Drag Race" host shared his top three most shocking moments in the history of the long-running competition show. Ru is the cover star for Entertainment Weekly's LGBT issue this month, and in an interview with the magazine, discussed what has surprised him the most over the years.

"The time that Roxxxy Andrews revealed her childhood trauma of being left at a bus stop by her mother when she was four years old - her and her sister," Ru says of the Season 5 queen.

"Then she went on to lip synch for her life," Ru goes on to say. "One of the greatest lip syncs of all time. She took her wig off. Only to reveal another wig underneath...It was beyond."

Ru then touched on a more recent moment - Season 9's controversial lip sync that saw contestant Valentina refusing to take off her mask.

"Another, of course, was Valentina lip syncing for her life, or should I say, notlip syncing for her life...I had to stop the lip sync and say, 'Madame we need to see your lips!" Ru said.

Ru rounded out the top three with a major throwback - all the way from Season 1. The Emmy Award-winning host recalled when Ongina revealed her HIV status.

"It was really amazing. We were not prepared for that," he says. "She won the challenge for the Viva Glam AIDS Foundation. Then she revealed her HIV status, which was so empowering and moving...she was such a hero - around the world."
